Coniferophyta is a division of the gymnosperms, which along with all other land plants were formed on the third day of creation. They are also called Pinophyta by some taxonomic systems. They consist of the conifers or plants that bear cones (a protective covering around a seed). Most are large trees while a few are shrubs and other small plants. Most of them have bark with softwood which protects the tree. They have a large economic use because of their softwood as well as hardwoods which are much more pleasing to many and used in furniture. Pinopsida is the only class of Pinophyta with living plants today.

Anatomy
The plants in coniferophyta are conifers, meaning they bear cones. Most of the plants in this division are large trees like the Coast Redwood which grow near to, or over 100 meters. The smaller plants may be as little as one meter. Most branches come from a main trunk or stem. The leaves of conifers are either needle-like or flat and triangular. They have lots of vascular tissue for transmitting water, nutrients, and sugar.
Reproduction
The name conifer comes from cone, which are reproductive organs that either bare pollen or seed. The pollen, which is the male reproductive part, is carried by the wind from one cone to a seed cone, which is the female reproductive part. They may be on the same tree. The pollen fertilizes the ovum which then becomes a seed. The seeds fall from the cone when they are mature. Some cones disintegrate and leave the seeds to grow. Some seeds wait until the plant burns up in a fire, leaving them. Some conifers produce pine nuts or fleshy scales to cover the seeds. As with other plants Pinophyta seeds are dispersed by birds, or small mammals.
Ecology
Most of the member of Coniferophyta live together over large areas in boreal forests near cool climates.
Uses
They is very important for our economy because of their softwood, which is used for paper and timber, and many people use cedar for their homes. The Bible records that the Cedar of Lebanon was used for temples or other extravagant structures. Some conifers excrete a resin, which is used for varnishes and adhesives, to protect itself from insects and fungal infections. Conifers are evergreens.
